The correct Answer is:
To solve the question regarding the attraction of bits of paper to a plastic scale rubbed with a carpet, we will break down the explanation step by step. ### Step-by-Step Solution: 1. **Understanding the Process of Rubbing**: - When a plastic scale is rubbed against a carpet, electrons are transferred between the two materials. This process is known as triboelectric charging. - Hint: Remember that rubbing two different materials can lead to the transfer of electrons, creating static electricity. 2. **Charge Generation**: - The plastic scale becomes negatively charged due to the gain of electrons, while the carpet becomes positively charged due to the loss of electrons. - Hint: Identify which material gains or loses electrons based on their position in the triboelectric series. 3. **Interaction with Paper**: - When the negatively charged plastic scale is brought near bits of paper, the electric field from the charged scale affects the neutral paper bits. - Hint: Consider how electric fields can influence neutral objects. 4. **Polarization of Paper**: - The presence of the negatively charged scale causes the charges within the paper bits to rearrange. The positive charges in the paper are attracted towards the scale, while the negative charges are repelled. - Hint: Think about how the distribution of charges within a neutral object can change in the presence of an external electric field. 5. **Resulting Attraction**: - This rearrangement of charges in the paper bits creates a dipole, where one side of the paper becomes positively charged and the other side becomes negatively charged. The attraction occurs because opposite charges attract. - Hint: Remember that opposite charges attract, leading to the attraction between the charged scale and the polarized paper. 6. **Conclusion**: - The attraction of bits of paper to the plastic scale is due to the polarization of the paper by the charged scale. The correct explanation is that the atoms in the paper get polarized by the charges of the scale, leading to attraction. - Hint: Summarize the key concept that polarization leads to attraction between charged and neutral objects. ### Final Answer: The attraction of bits of paper to a plastic scale rubbed with a carpet is due to the polarization of the paper by the charged scale.

What kind of electric charge is acquired : by a plastic comb rubbed with dry hair ?

We have two identical metal sheets. One of them is rubbed with sand paper and the other with ordinary paper. The one rubbed with sand paper shines more than the other. Give reason.

Geeta has dry hair. A comb ran through her dry hair attracts small bits of paper. She observes that Neeta with oily hair combs her hair, the combs could not attract small bits of paper. She consults her teacher for this and gets the answer. She then goes to the junior classes and shows this phenomenon as physics experiment to them. All the juniors feel very happy and tell her that they will also look for such interesting things in nature and try to find the answer. She succeeds in forming a science club in her school. Read the above passage and answer the following questions. (i) What according to you are the values displayed by Geeta? (ii) Explain the phenomenon involved.
